A map of the Indonesia’s mountains in their full glory. This trip will cover Sumatra only and we are not going to volcanoes where guides are mandatory (e.g. Kerinci) or women are forbidden (e.g. Sorikmarapi).

There are four Ribu categories, three based on their absolute elevation and a fourth ‘Spesial’ category for peaks which are considered to be of special interest. Check the Methods page for more information on the analysis of prominence.
